The <tt>[[mu|mailutils]] logger</tt> tool logs information using Mailutils log facility. Syntax: mailutils logger [''options''] [''message''] The ''message'' argument, if supplied, gives the text to log. If not supplied, the utility reads lines of text from standard input or a file (if the <tt>--file</tt> option is given) and sends them to log: # Send text to log $ mailutils logger I am here # Log each line from file.txt $ mailutils logger --file file.txt # Read stdin and log it: $ mailutils logger The default logging channel is bound to standard error. To bind it to syslog, use the <tt>--syslog</tt> command line option. In that case <tt>mailutils</tt> uses facility <tt>user</tt> and priority <tt>err</tt>. You can change this by using the <tt>--priority</tt> (<tt>-p</tt>) option. Its argument is either a syslog facility name or facility and severity names separated by a dot. Thus, the following invocation will use facility <tt>auth</tt>, severity <tt>info</tt>: mailutils logger --priority auth.info The syslog tag can be set using the <tt>--tag</tt> (<tt>-t</tt>) option: mailutils logger --tag myprog The default tag is <tt>mu-logger</tt>. The <tt>--severity</tt> (<tt>-s</tt>) option sets the Mailutils severity level. Its argument can be any of the following strings: <tt>debug</tt>, <tt>info</tt>, <tt>notice</tt>, <tt>warning</tt>, <tt>error</tt>, <tt>crit</tt>, <tt>alert</tt>, <tt>emerg</tt>. Finally, the <tt>--locus</tt> (<tt>-l</tt>) option binds log messages to a location in a file. Its argument has the following syntax: ''file'':''line''[.''col''][-[''file'':]''line''[.''col'']] where ''file'' is the file name, ''line'' is the line number and optional ''col'' is the column number in that file. For example, the following invocation: mailutils logger --locus mailutils.rc:34 Suspicious statement will send the following to the log: mailutils-logger: mailutils.rc:34: Suspicious statement == See also == * [[mailutils (utility)]] [[Category:utilities]]
